The gears are so arranged that necosszu'y. mijustnients. A motion vpicture the disks 17, 23 and 24 will rotate with ns nppurziius 14 inounted on the houf-:ing 10 greata speed as the rolicrs 49' end 51' Cil ` the `roller 49' the pin 27' `13 the roller 5% .the in A27' which govern the speed of the film 13. The rollers 49' and 51" are provided with pins 5:3 which engage with perforations 53' provided in the iil'm 13 and prevents the said lilni i'roin slpping and provides a steady niovcmcnt ot' the film. Swingingly inounted on the side wall 12 is a roller 54 held in engageinent with hy a spring 55. The roller 54 is arranged to throw out of engagement, when the portion (52 ot' the fihn 13 is tightened, a dog 56 which engages with a notch 57 provided on the disk 17.

In operation the ends of the film 13 are sccux'ed together by cement or any other suitable material, forming a continuous film. The film 13 is then' wound on the pins 26 and 26' carried on the disk 23, in the manner illustrated in Fig. 8 of the drawings. After the film 13 has been completely wound intlo a reel the portion 62 of the ilm 13 passes around the pin 27 carried on the disk 24 and around the roller 51' through a guide nieniber 59 passing over a roller and around and then rewindingir on the pins 27 and 27' after the disk 24 has been shifted into winding position. The disk 23 as illustrated in Fig. 1 of the drawings has completed its winding'` operation and is now ready to be swung into a position where the said film will go through the unwinding operation. This is accomplished by the tightening of the portion. 62 of the film 13 between the pin 27 and the roller 51. By the tightening of the portion 62 of the film is forced backwards and raises the dog 56 which holds the disk 17 stationary while the film 13 is wound and unwound. When thev fihn 13 is completely unwound from the pins 27 and 27' and completely wound upon the pins 26 and 26'. the portion of the fihn between the film reel 1.'- and the roller 51' becomes taut to such an cxtent that the`pin 27 is forced upwardly causing the saw-toothed gear 18 to mosh with the saw'toothed gear 45, lrotating the disk 17 which carries the disk 24' into winding position. A portion of the teeth on the gear 18 are cut away to allow the gear 18 to idle when the film 13 goes through its winding and unwinding operation. When the disk 24, which is carried by the disk 17, is swunginto winding position the dog 34 engages with 8. pin 61, mounted on the side wall 12, disengaging the dog' 34 with the groove 36 and the resilient spring 30 forces in so as to allow the pin 27' to free y pass under the portion 62 of the tilm 13. At the desired point the. head 29 of engages with a cam 62' provided on the side wall 12 and is fort-ed hack into operative position and engages With the film 13 as shown by dotted-line in Fig. 1 of the drawings. After the disk 24 is swunginto winding position and the disk 23 is swung a por'zion 62 of the film 13.

into unwinding position the portion 62 .of thev film 13 loosens and 'a spring 55 forces the roller 54 backward allowing the dog 56 to engage ,with the notch 57 holding the disk 17 stationary. The gear 37 mounted on the shaft 21 which is rigidly fixed to continues to rotate the 'disk 23 01'24 until the film 13 is completely wound and swung into its unwinding position.
